commons-compress实现zip文件分卷压缩的示例代码

以下是使用Java的commons-compress库实现zip文件分卷压缩的示例代码：

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
import org.apache.commons.compress.archivers.zip.ZipArchiveOutputStream;
import org.apache.commons.compress.utils.IOUtils;

public class ZipFileSplitter {
    private static final int BUFFER_SIZE = 4096;
    private static final int MAX_SEGMENT_SIZE = 10 * 1024 * 1024; // 10 MB

    public static void splitZipFile(File inputFile) throws IOException {
        FileInputStream fileInputStream = new FileInputStream(inputFile);
        BufferedInputStream bufferedInputStream = new BufferedInputStream(fileInputStream);
        ZipArchiveOutputStream zipArchiveOutputStream = new ZipArchiveOutputStream(new BufferedOutputStream(new FileOutputStream(inputFile.getName() + ".zip")));
        zipArchiveOutputStream.setMethod(ZipOutputStream.DEFLATED);
        int currentSegment = 0;
        long currentSegmentSize = 0;
        byte[] buffer = new byte[BUFFER_SIZE];
        ZipEntry entry;
        while ((entry = zipArchiveOutputStream.getNextEntry()) != null) {
            zipArchiveOutputStream.putArchiveEntry(entry);
            int count;
            while ((count = bufferedInputStream.read(buffer, 0, BUFFER_SIZE)) != -1) {
                zipArchiveOutputStream.write(buffer, 0, count);
                currentSegmentSize += count;
                if (currentSegmentSize >= MAX_SEGMENT_SIZE) {
                    zipArchiveOutputStream.closeArchiveEntry();
                    zipArchiveOutputStream.finish();
                    zipArchiveOutputStream.close();
                    currentSegment++;
                    currentSegmentSize = 0;
                    zipArchiveOutputStream = new ZipArchiveOutputStream(new BufferedOutputStream(new FileOutputStream(inputFile.getName() + ".part" + currentSegment + ".zip")));
                    zipArchiveOutputStream.setMethod(ZipOutputStream.DEFLATED);
                    entry = new ZipEntry(entry.getName());
                    zipArchiveOutputStream.putArchiveEntry(entry);
                }
            }
            zipArchiveOutputStream.closeArchiveEntry();
            zipArchiveOutputStream.finish();
            zipArchiveOutputStream.close();
            bufferedInputStream.close();
            fileInputStream.close();
        }
    }

    public static void main(String[] args) {
        try {
            File inputFile = new File("example.txt");
            splitZipFile(inputFile);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

该示例代码可以将一个zip文件分割成多个部分，每个部分最大为10MB，并将它们压缩成单独的zip文件。该代码使用了commons-compress库的ZipArchiveOutputStream类来创建压缩文件，使用了ZipEntry类来表示每个条目，并使用了缓冲输入流和缓冲输出流来提高读写效率。
